Anne -

I suggest you study our 2004 PLOS.org paper on ICA decomposition of 'a' P300 response from a visual spatial selective attention task. We reported  contributions to the P300 feature of the ERP from at least 8 distinct 
classes of (independent) EEG processes. So, to study the amplitude of 'P300' in single trials, the question would be, contributions to the P300 ERP feature from which 
class(es) of processes?
